Powerware 6000 VA, 5000 manual Bypass

TROUBLESHOOTING

Alarm or Condition Possible Cause Action

Bypass UPS is in Bypass mode.

The equipment is transferred to utility power; however, the utility power continues to be passively filtered by the UPS. Check for one of the following alarms: Overtemperature, Overload, or UPS Failure.

The UPS automatically returns online after the condition is cleared. However, if the UPS transfers to Bypass mode 3 times in 1 hour, the UPS remains in Bypass mode until the UPS On button is pressed or the 1-hour timer expires.

NOTE If Bypass mode is due to a UPS failure, frequency conversion (FC) UPS models no longer convert the utility frequency to the load.

Bypass	Bypass is not available. Input
	voltage is not within ±12% of
	nominal or input frequency is
	not within ±3% of nominal.

The UPS is receiving utility power that may be unstable or in brownout conditions. The UPS continues to supply power to your equipment. If conditions worsen, the UPS may switch to battery power.

Battery Service	The battery may be fully
	discharged.

Plug the UPS into a power outlet (apply utility power on hardwired models) for 24 hours to charge the battery.

After charging the battery, press and hold the			button
for 3 seconds; then check the		indicator.
If the	indicator is still on, see “UPS Maintenance” on

page 41 to replace the battery.

The battery is not connected correctly or the battery circuit breaker is open.

Verify that the internal batteries are installed correctly (see page 16) and that the battery circuit breaker is in the ON ( ) position. Call your service representative if the problem persists.

Site Wiring Fault (North American models only)

Ground wire connection does not exist or the line and neutral wires are reversed in the wall outlet.

Have a qualified electrician correct the wiring.

To disable this alarm, see “Configuration” on page 35.

UPS internal temperature is

Overtemperature too high. The UPS switches to Bypass, allowing the UPS to cool.

Clear vents and remove any heat sources. Ensure the airflow around the UPS is not restricted. If the condition persists, contact your service representative.

Overload

Continuous audible alarm

Power requirements exceed UPS capacity (103–112% for

2 minutes; 112–150% for up to

30 seconds) or the load is defective.

Remove some of the equipment from the UPS.

If the overload condition persists, the UPS automatically shuts down.
